Function Documentation

int elf_core_save	(	const char *	file_name,
		as_area_info_t *	ainfo,
		unsigned int	n,
		int	phoneid
	)

Save ELF core file.

Parameters:

	file_name	Name of file to save to.
	ainfo	Array of n memory area info structures.
	n	Number of memory areas.
	phoneid	Debugging phone.

Returns:

EOK on sucess, ENOENT if file cannot be created, ENOMEM on out of memory, EIO on write error.

Definition at line 81 of file elf_core.c.

static char * fmt_sym_address

(

uintptr_t

addr

)

[static]

Format address in symbolic form.

Formats address as <symbol_name>+<offset> (<address>), if possible, otherwise as <address>.

Parameters:

addr

Address to format.

Returns:

Newly allocated string, address in symbolic form.

Definition at line 459 of file taskdump.c.

int main	(	int	argc,
		char *	argv[]
	)

Main entry point.

Returns:

Zero on success, non-zero on error.

Definition at line 75 of file taskdump.c.

static int write_all	(	int	fd,
		void *	data,
		size_t	len
	)			[static]

Write until the buffer is written in its entirety.

This function fails if it cannot write exactly len bytes to the file.

Parameters:

	fd	The file to write to.
	buf	Data, len bytes long.
	len	Number of bytes to write.

Returns:

EOK on error, return value from write() if writing failed.

Definition at line 265 of file elf_core.c.

static int write_mem_area	(	int	fd,
		as_area_info_t *	area,
		int	phoneid
	)			[static]

Write memory area from application to core file.

Parameters:

	fd	File to write to.
	area	Memory area info structure.
	phoneid	Debugging phone.

Returns:

EOK on success, EIO on failure.

Definition at line 223 of file elf_core.c.
